摘要： 建立了当边缘路由器采用E2CN拥塞控制的机制时TCP连接时延的数学模型。在理论上分析了运用这种机制能够降低连接时延的原理,给出了拥塞机制中参数对TCP连接时延的影响。通过仿真表明,提出的新的时延模型相当精确,为能更好设计出符合IPQoS要求的TCP协议应用提供了理论依据。

Abstract: This paper sets up a mathematical model which describes the latency of TCP connection, when the edged router adopts the E2CN congestion control algorithm. The model is verified using the simulation of the TCP connection, and the analyzing results are useful to design new TCP protocol application which can be helped to the research of IP QoS.
